Fig. 2 Loss of lmo4b causes forebrain and eye enlargement. (A, B) Lateral view of 10-somite embryos injected with 4 ng of 4 mm-MO (A) and 4 ng of lmo4b-MO (B). (C) Quantitative representation of eye diameter (ED) and head height (HH) measurements of embryos injected with 4 mm-MO (blue) and lmo4b-MO (red). Error bars represent standard error of the mean (S.E.M.). Values in μm with confidence intervals for head height are 131 ± 8 for control injections and 162 ± 12 for morphants, and for eye diameter are 125 ± 10 for control injections and 164 ± 12 for morphants. For HH p = 8.7 x 10- 5, for ED p = 2.2 x 10- 5. (D–O) Whole mount views of embryos injected with 4 mm-MO (D, F, H, J, L, N) and lmo4b-MO (E, G, I, K, M, O) show size differences in the forebrain and eyes. Panels D, E, and J–M are lateral views. Panels F–I are dorsal views of the anterior region, and panels N, O are ventral views of the anterior. The dashed lines in panels L, M represent pre-optic area. tel = telencephalon; di = diencephalon. Scale bars are 20 μm.
